Solar Fuels

via Photoelectrochemical devices

To enable a sustainable society based primarily on solar energy, methods to store sunlight as chemical fuels are needed. Photoelectrochemical (PEC) devices offer the promise of solar fuel production through artificial photosynthesis. While the idea of carbon-neutral energy economy powered by the “artificial leaf” is intriguing, viable PEC energy conversion on a global scale requires the development of a device with simplicity, stability, and high efficiency. LIMNO works to advance the field of PEC solar fuel production by developing specific classes of promising semiconducting materials (e.g. transition metal dichalcogenides, organic semiconductors, and metal oxide semiconductors). In addition, LIMNO’s research focuses on understanding and improving the operation of overall PEC devices via interface engineering and advanced photoelectrochemical strategies/techniques. See specific examples of our research reports below.
